Peafowl

About the peafowl

The Indian peafowl is the bird most people picture when they hear "peacock" — though, technically, peacock refers only to the male. Females are peahens, and the pair together are peafowl. It's a member of the pheasant family, Phasianidae, and one of the heaviest birds in that family: males measure 100 to 120 cm (40 to 46 in) from bill to tail and, with a fully grown train, stretch to 200 to 230 cm (78 to 90 in), weighing 4.1 to 5.2 kg (9 to 11.5 lb). Females are considerably smaller, at around 97 cm (38 in) and 2.7 to 4.1 kg (6 to 9 lb).

The species shows striking sexual dimorphism. The male has a metallic blue crown topped with a fan-shaped crest of bare black shafts tipped in bluish-green, a white eye stripe, a long blue neck with scaly bronze-green feathering, and chestnut-and-black wings. His signature feature — the train — isn't actually his tail but a set of elongated upper-tail-covert feathers, bronze-green with eye-spots of purplish-black ringed in blue and copper, that don't finish developing until his fourth year and are molted and regrown annually starting around the end of the monsoon. The train's iridescent color comes from microscopic feather structure rather than pigment. The peahen, by contrast, is mostly brown with a rufous-brown crested head, a metallic green lower neck, and no train at all.

Native to the Indian subcontinent, the species is found across most of India and Sri Lanka, from the Indus valley in the northwest to Assam in the northeast and from the Himalayas down to the southern tip, absent mainly from the Sunderbans marshlands. It ranges up to 5,000 ft (1,500 m) in the north and 6,000 ft (1,800 m) in the southern mountains, in forests, small hills, bushy country near water, and cultivated land, sometimes living semi-domesticated around human settlements. It has since been introduced widely elsewhere and has gone feral in some of those places — a spread credited, in part, to Alexander the Great, who may have carried the bird into Europe, where it had reportedly reached Athens by 450 BCE.

Behavior and diet

Peafowl forage on the ground in small groups called musters, typically one peacock with three to five peahens; after breeding season, flocks tend to be all females and young. They're active in the open early in the morning, rest under cover through the heat of the day, and are often seen dust-bathing at dusk. They roost in tall trees at night — sometimes on rocks or buildings instead — arriving at dusk and calling frequently before settling in. Despite their size and train, peafowl can fly, using slow, deliberate wingbeats rather than gliding, though they generally prefer to run through undergrowth when disturbed rather than take off.

The diet is omnivorous: grass, seeds, flowerbuds, fruit, insects, and small reptiles, with local diets shifting toward whatever's available — Zizyphus berries in the Gir forest, or crops like peanut, tomato, rice, chili pepper, and banana near farmland. Around human settlements, birds also scavenge food scraps. Calls are loud and varied — a common pia-ow or may-awe, more frequent before the monsoon, plus a rapid ka-aan..ka-aan, a kok-kok, and an explosive honk when agitated — and are often used across the group to flag a predator such as a tiger.

Breeding follows the onset of monsoon rains. The peacock is polygamous, and related males gather at a lek, holding small adjoining territories that females visit — without any male attempting to guard a harem. Courtship centers on the train: the male raises it into an arched, quivering fan, drops his wings, faces the peahen, and periodically vibrates the long feathers to produce a rustling sound; he may also freeze over food to invite the female closer, a form of courtship feeding. Peahens frequently seem uninterested, continuing to forage during a display. Nests are shallow ground scrapes lined with leaves and sticks, sometimes built in building crevices or old vulture nests; a female lays three to eight eggs, incubates them alone for 28 to 30 days, and the male takes no part in either incubating or rearing the young. Chicks can walk and follow their mother almost immediately, and downy young sometimes ride on her back or get carried in flight to a safe branch.

Range and habitat

The Indian peafowl is native to the Indian subcontinent, found across most of India — from the Indus valley to Assam, and from the Himalayas to the southern tip, except the Sunderbans marshlands — and across Sri Lanka, where it favors the drier lowlands. It lives up to 5,000 ft (1,500 m) in northern India and 6,000 ft (1,800 m) in the southern mountains, occupying forest, small hills, bushy country near water sources, and cultivated land, and it often lives in a semi-domesticated state around human habitation.

The species has been introduced across much of the rest of the world and has established feral populations in some of those places. Historically it may have reached Europe with Alexander the Great, and records suggest it had reached Athens by around 450 BCE.

Conservation status

The Indian peafowl is listed as Least Concern on the IUCN Red List, in a 2016 assessment by BirdLife International. It is widespread across India and Sri Lanka, with feral colonies in many parts of the world. A conservative 2002 estimate put the wild population above 100,000, and it is not thought to be declining.

Known threats include poaching for meat and feathers, use in folk remedies and accidental poisoning from pesticide-treated seed. The bird can also clash with people, cutting rice yields by up to 40 percent in some fields and damaging gardens and cars in towns.

It is protected both culturally and by law in India and Sri Lanka. It is India's national bird and is venerated in Hindu and Greek mythology. Indian law allows only naturally shed feathers to be collected, and sanctuaries such as Choolannur Pea Fowl Sanctuary and Viralimalai Bird Sanctuary protect it.
